SVG

Scalable Vector Graphics (SVG) is an XML-based markup language for describing two dimensional based vector graphics. SVG is essentially to graphics what HTML is to text.

SVG is a text-based open Web standard. It is explicitly designed to work with other web standards such as CSS, DOM, and SMIL.

SVG images and their related behaviors are defined in XML text files which means they can be searched, indexed, scripted and compressed. Additionally this means they can be created and edited with any text editor and with drawing software.
